The answer to 'natural emergency pest control repellent' is to use essential oils as a natural pest repellent. Oils like peppermint, citronella, lemongrass, or cedarwood can help deter insects and rodents from your home. Apply these oils around entry points, under sinks, and in other problem areas.
Be sure to use the oils safely by diluting them in a carrier oil and spot-testing first to check for skin irritation. Reapply the oils every few days or as needed to maintain their effectiveness. If the pest problem persists, it's best to call in a professional pest control technician who can properly identify and eliminate the issue.
